Display Response Times

ℹ

Display response times show how fast the screen is able to change from one color to the next. Slow response times can lead to afterimages and can cause moving objects to appear blurry (ghosting). Gamers of fast-paced 3D titles should pay special attention to fast response times.

↔ Response Time Black to White

31.2 ms ... rise ↗ and fall ↘ combined

↗ 17.2 ms rise

↘ 14 ms fall

The screen shows slow response rates in our tests and will be unsatisfactory for gamers.In comparison, all tested devices range from 0.8 (minimum) to 240 (maximum) ms. » 79 % of all devices are better.This means that the measured response time is worse than the average of all tested devices (25.4 ms).

↔ Response Time 50% Grey to 80% Grey

22.4 ms ... rise ↗ and fall ↘ combined

↗ 10.8 ms rise

↘ 11.6 ms fall

The screen shows good response rates in our tests, but may be too slow for competitive gamers.In comparison, all tested devices range from 0.9 (minimum) to 636 (maximum) ms. » 11 % of all devices are better.This means that the measured response time is better than the average of all tested devices (40.6 ms).

Screen Flickering / PWM (Pulse-Width Modulation)

ℹ

To dim the screen, some notebooks will simply cycle the backlight on and off in rapid succession - a method called Pulse Width Modulation (PWM) . This cycling frequency should ideally be undetectable to the human eye. If said frequency is too low, users with sensitive eyes may experience strain or headaches or even notice the flickering altogether.

Screen flickering / PWM not detected

In comparison: 51 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 9590 (minimum: 43 - maximum: 142900) Hz was measured.

(±) The average temperature for the upper side under maximal load is 32.7 °C / 91 F, compared to the average of 30.7 °C / 87 F for the devices in the class Subnotebook.(±) The maximum temperature on the upper side is 40.9 °C / 106 F, compared to the average of 35.8 °C / 96 F, ranging from 22 to 57 °C for the class Subnotebook.(+) The bottom heats up to a maximum of 38.1 °C / 101 F, compared to the average of 40.1 °C / 104 F(+) In idle usage, the average temperature for the upper side is 23.1 °C / 74 F, compared to the device average of 30.7 °C / 87 F.(±) Playing The Witcher 3, the average temperature for the upper side is 34.8 °C / 95 F, compared to the device average of 30.7 °C / 87 F.(+) The palmrests and touchpad are cooler than skin temperature with a maximum of 28.6 °C / 83.5 F and are therefore cool to the touch. (±) The average temperature of the palmrest area of similar devices was 28.6 °C / 83.5 F (0 °C / 0 F).
